# Thingfish PostgreSQL Metastore

## Description

This is a metadata storage plugin for the Thingfish digital asset

manager.  It provides persistent storage for uploaded data to

PostgreSQL tables.

It is heavily based on the regular PG metastore, however it differs by

storing objects as nodes, and their relations as edges.

## Authors

* Michael Granger <ged@FaerieMUD.org>

## Installation

    $ gem install thingfish-metastore-pggraph

##  Usage

As with Thingfish itself, this plugin uses

Configurability[https://rubygems.org/gems/configurability] to modify

default behaviors.

Here's an example configuration file that enables this plugin.

        ---

        thingfish:

          metastore: pggraph

          pggraph_metastore:

            uri: postgres://thingfish:password@db.example.com/database

When Thingfish starts, it will install the necessary database schema

automatically.
